X
Briefly pull the cruise control lever towards
you ?or press it up :or down Ato the
pressure point.
Distronic is activated.
X Keep the cruise control lever pressed
up : or down Auntil the desired speed
is set.
X Remove your foot from the accelerator
pedal.
Your vehicle adapts its speed to that of the
vehicle in front, but only up to the stored
speed.
i You can use the cruise control lever to set
the stored speed and the thumbwheel on
the cruise control lever to set the specified
minimum distance (Y page 123).
i If you do not fully release the accelerator
pedal, the DISTRONIC Override message
appears in the multi-function display. The
distance to a slower-moving vehicle in front
will then not be governed. You will be driv-
ing at the speed you determine by the posi-
tion of the accelerator pedal.
Driving
If there is no vehicle in front, Distronic oper-
ates in the same way as cruise control.
If a slower-moving vehicle is detected in front,
Distronic causes your vehicle to brake and
maintain the preset distance to the vehicle in
front.
If Distronic detects a faster-moving vehicle in
front, it increases the driving speed, but only
as far as the stored speed. G
Risk of accident
If you depress the brake pedal, Distronic is
deactivated. Distronic will then no longer
brake your vehicle. The driver is fully respon-
sible for the vehicle's distance from other
vehicles, its speed and for braking in good
time. Stopping G
Risk of accident
The Distronic braking effect is cancelled and
the vehicle can start moving if:
R Distronic is deactivated using the cruise
control lever.
R you accelerate.
R the system or the power supply is disrup-
ted, e.g. due to battery failure.
R the electrical system in the engine com-
partment or the fuses have been tampered
with.
R the battery is disconnected. G
Risk of accident
Distronic must never be operated or deacti-
vated by a passenger or from outside the vehi-
cle.
If you wish to leave the vehicle or park it,
deactivate Distronic and secure the vehicle
against rolling away.
If Distronic detects that the vehicle in front is
stopping, it brakes your vehicle until it is sta-
tionary.
i Depending on the specified minimum dis-
tance, your vehicle will come to a standstill
about four metres behind the vehicle in
front. The specified minimum distance is
set using the thumbwheel on the cruise-
control lever.
Distronic is deactivated automatically when
stopping:
R on flat stretches of road or on downhill gra-
dients when the vehicle is stationary.
R while the vehicle is still moving on uphill
gradients, to prevent the vehicle from unex-
pectedly rolling back when Distronic is
deactivated.
If Distronic is deactivated, you will hear a
warning tone.

that speed is and whether it is suitable for the
current situation. Otherwise, sudden acceler-
ation or braking could endanger you or others.
X Briefly pull the cruise control lever towards
you ?.
X Remove your foot from the accelerator
pedal.
Distronic is activated and accepts the cur-
rent speed if it is activated for the first time,
or adjusts the vehicle's speed to the last
speed stored. Setting the specified minimum dis-
tance for Distronic You can set the specified minimum distance
for Distronic by varying the time span
between one and two seconds. This time span
determines the distance that Distronic should
maintain from the vehicle in front, depending
on the road speed. You can see this distance
in the multi-function display (Y
page 124). X
To increase: turn thumbwheel ;towards
=.
Distronic then maintains a greater distance
between your vehicle and the vehicle in
front.
X To decrease: turn thumbwheel ;

Tips for driving with Distronic The following contains descriptions of certain
road and traffic conditions in which you must
be particularly attentive. In such situations,
brake if necessary. Distronic is then deacti-
vated.
Cornering, entering and exiting a bend
The ability of Distronic to detect vehicles
when cornering is limited. Your vehicle may
brake unexpectedly or too late. Vehicles travelling on a different line
Distronic may not detect vehicles travelling
on a different line. The distance to the vehicle
in front will be too short.
Other vehicles changing lane
Distronic has not yet detected the vehicle
cutting in. The distance to this vehicle will be
too short.

Adapt your driving style to suit the vehicle
level. ESP ®
cannot reduce the risk of an acci-
dent if you drive too fast. ESP ®
cannot over-
ride the laws of physics.
! When driving on extremely rough terrain,
select a high vehicle level in good time.
Make sure there is always sufficient ground
clearance to prevent damage to the vehi-
cle.
You will find information about driving off-
road in the "Operation" section
(Y page 188).
Basic settings The extent to which the vehicle is raised or
lowered depends on the basic setting selec-
ted.
Select:
R Off-road level 3 for freeing the vehicle in
impassable terrain at low speeds only
R Off-road level 2 for driving on normal off-
road terrain
R Off-road level 1 for driving on easily nego-
tiable off-road terrain
R Highway/high-speed level for normal roads
The individual vehicle levels are:
R Off-road level 3: 90 mm above highway
level
R Off-road level 2: 60 mm above highway
level
R Off-road level 1: 30 mm above highway
level
R Highway level: +/- 0 mm
R High-speed level: 15 mm below highway
level Off-road levels G
Risk of accident
Off-road level 3 is not permitted for use on
public roads. Off-road level 3 gives your vehi-
cle a very high centre of gravity. This increa-
ses the risk of the vehicle tipping over.
R Only select off-road level 3 for driving off-
road in particularly rough terrain.
R Adjust your driving style to the altered han-
dling characteristics.
R Do not drive faster than 20 km/h.
R Avoid sudden major steering movements.
R Take account of the altered handling char-
acteristics.
If you are driving too fast in off-road level 3,
the Bring speed below 20 km/h message
appears in the multi-function display. You
additionally hear a warning tone. The vehicle
is lowered.
i You cannot clear these messages.
Only select an off-road level when this is
appropriate for the road conditions. Other-
wise, fuel consumption increases and han-
dling performance may be affected.
Your selection remains stored even if you
remove the key from the ignition lock. 130

G
Risk of accident
PARKTRONIC is only an aid and may not
detect all obstacles. It is not a substitute for
attentive driving.
You are always responsible for safety and
must continue to pay attention to your imme-
diate surroundings when parking and
manoeuvring. You could otherwise endanger
yourself and others. G
Risk of injury
Make sure that no persons or animals are in
the manoeuvring range. Otherwise, they
could be injured.
PARKTRONIC is an electronic parking aid
using ultrasound. It indicates visually and
audibly the distance between your vehicle
and an object.
PARKTRONIC is activated automatically when
you:
R switch on the ignition
R release the parking brake
R shift the automatic transmission to D,Ror
N
PARKTRONIC is deactivated at speeds above
18 km/h. It is reactivated at lower speeds.
PARKTRONIC monitors the area around your
vehicle using six sensors in the front bumper
and four sensors in the rear bumper. :
Example: sensors in the front bumper,
